Complete Healthcare International (CHI) | Singapore pg. 1 Coughing Up Phlegm Causes and Treatment | CHI SG A persistent cough that produces phlegm is one of the most common yet frequently overlooked respiratory symptoms affecting people of all ages.

Complete Healthcare International (CHI) in Singapore provides thorough medical evaluation and personalise d care for patients dealing with ongoing cough and respiratory concerns. What Does Coughing Up Phlegm Actually Mean? Phlegm is a thick mucus produced by the lining of the respiratory tract. When the airways become inflamed or infected, the body generates e xcess mucus as a protective response, which is then expelled through coughing. The colour, consistency, and frequency of phlegm can all provide important clues about what is happening inside the body. Clear or white phlegm often indicates a viral infection or mild irritation, while yellow or green mucus may suggest a bacterial infection requiring targeted treatment. Brown or blood tinged phlegm warrants immediate medical assessment. Understanding these variations is an important first step in identifying th e correct coughing up phlegm causes and treatment path.
